Device reboot in strange way


#1

Hi, have encountered a strage reboot from the device. It seems that ETH port goes up and down… and the system seems to restart

the logs are here down…

Hi Thesok,

Please go to Diagnostics > Logs > Support Info > click the blue Support Files button to download a .tar file from each radio to your local computer, and then email the files to support@mimosa.co.

This message means that a process stopped, the system could not restart it, and the radio rebooted to recover itself: “MIMO_EVENT Shutdown reason: Too many retries to restart a daemon - Cannot rescue hostapd.”

The detailed logs will tell us why, and depending on the reason and firmware version, we may have already solved it. Please send the logs and we will let you know.

What was the fix? I’m having TDWR problems as well. This radio is 66 miles from the closest Doppler and is facing a different direction.

Hi Alan,

After receiving the support logs, we traced the problem above ("…Cannot rescue hostapd") to a firmware bug that was fixed in the version 1.4.1 release. The TDWR line in the file above is displayed on every bootup before association. It is normal to see that (not an error), and it is completely unrelated.

Please email your support logs (.tar files) to support and they will diagnose the problem for you.
